The ? Block is an interactive decor item that doubles as a table. It is part of the Mario Theme, and is obtained by buying a fortune cookie for 2 Play Coins, and turning in fortune #25. It can be sold for 210 Bells at Re-Tail (168 Bells at Nooklings).

When interacted with, it makes the sound of an item coming out of a ? Block as in the Mario games. The sound can be heard below.

In the popular gaming franchise Super Mario Bros., ? Blocks are found all around, usually with blocks. When struck from below, the block will eject an item from the top, ranging from power-ups such as the mushroom, fire flower, and starman, to other useful things like coins and 1-ups. The model used in Animal Crossing: New Leaf is most likely from the New Super Mario Bros. games.
